And to answer the original question - we now have a number of volumes  
which are pushing 100GB in actual usage. Other than the fact that  
they take a long time to move, copy, back up, etc, they work fine.  
After our backup system barfed on a 121GB volume, we have capped  
volumes at 100GB max quota.  We're running 1.4.X.

My seat-of-the-pants analysis says the primary performance problem  
with these large volumes is all the old small-cache clients we have  
out there.
